AV_ADD: The address used to geocode the center to a GIS map. **Note: one address in this field was changed in order to achieve a match!

AV_STATUS: Geocode matching status--M = matched, U = unmatached.

AV_SCORE: The geocoding score derived by arcview when geocoding a table of addresses to a map.

AV_SIDE: The side of the street to which the point falls (L = left, R = right), depending on the direction of digitization of the arc segment.

Data Source History:
Mike Cassidy, OHHS, supplied Andrew Hopkins, OCIS, and Jonathan Lowe, Local Knowledge Consulting, with a Microsoft Excel spreadsheet containing a partial listing of Oakland's childcare centers. He supplemented this data with a paper brochure detailing additional Oakland headstart centers. Jonathan and Andrew then combined the two sources into a comprehensive table in ArcView and geocoded this table into a shapefile called "chldcare.shp." Jonathan then converted the shapefile into an Arc/Info coverage (its present format).Mike Cassidy reported that the childcare centers are updated approximately once each year in September. He then updates his excel spreadsheet as needed.

Quality Check:
Centers with addresses that did not match during the geocoding process were telephoned to verify the address and corrected as necessary to achieve a match. Addresses that were confirmed but did not match were left unmatched or were manually placed, independent of address-matching. Jonathan Lowe and Andrew Hopkins performed these quality control steps.

Security restrictions:
No security restrictions

Update Frequency:
Yearly, in September

Update process:
Mike Cassidy, OHHS, contacts OCIS and supplies a new spreadsheet of centers. OCIS GIS staff then geocode the new centers and append them to the current layer. The updated layer is filed on the k-drive.
